Bond Properties of NHL-Based Mortars with Viscosity-Modifying Water-Retentive Admixtures

This article studies the influence of biopolymeric viscosity-modifying admixtures with water-retentive function on physico-mechanical properties natural hydraulic lime-based mortars and their adherence to traditional fired-clay brick substrate. The use increases water/binder ratio, which in turn leads a decrease strength mortars. improves adhesive between mortar pre-wetter by increasing binder paste viscosity, while along increased water content may lead strength. On contrary, retention are beneficial dry surface, viscosity plays only minor role. When subjected temperature-varying cycles, more prone in-mortar failure during pull-off test. air-entraining some frost resistance mortars; however, it would negatively affect incorporating pores into contact zone study showed that studied improve adhesion
